Abstract

The embodiment of the invention discloses a power fault recording storage method and device, which are applied in the field of power systems. The power fault recording storage method comprises the steps that a collection module collects interruption data and circularly records the interruption data into a buffer stack; a recording module reads waveband data in the buffer stack at the fixed time, records the waveband data into a waveform buffering, sends an inform signal when the waveform buffering is written fully, and saves the data in the waveform buffering into a buffering queue, and the waveband data includes unread interruption data; and a storage module reads the data in the buffering queue and stores the data into a storage space after receiving the inform signal. According to the embodiment of the power fault recording storage method and device, the data is prevented from being lost, and the real-time and stable purposes can be achieved.

Description

technical field [0001] The invention relates to the field of power systems, in particular to a method and device for recording and storing electric fault waves. Background technique [0002] With the increasing scale of the power grid, a power grid fault information comprehensive analysis system capable of accurately diagnosing faulty components, analyzing post-accident data, and evaluating protection actions plays a very important role in the safe and reliable operation of the power system. [0003] In the prior art, a power fault recording and storage device called a power system black box can record the voltage, current waveforms and switching values ​​before and after a power system fault by interrupting the collection, and completely reflect the instantaneous changes after the fault And the action behavior of relay protection for later analysis. [0004] However, due to the large amount of data that needs to be recorded by the power failure recording and storage device...
